s/IPHON.

To all 'wlw/m, it may concern.

Be it known that I, JOHN F. BROWN, a, citizen -of the United States, residing at Casa Grande, in the county of Pinal and State of Arizona, have invented certain new and useful Improvements in Siphons; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to siphons and more particularly to aportable Siphon especially designed for irrigating purposes to conduct water from the irrigating ditches to the land to be irrigated.

The invention has for its object to provide a novel and efficient type of siphonespecially designed for irrigating purposes and including a pump and means for detachably connecting the pump cylinder vto the effluent end'of the Siphon, whereby the lair may be exhausted from the latter and water drawn therein.

With these and other objects in View, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter' specifically' described,`claimed and illustrated in the accompanying drawing', in which:

Figure 1 represents a side elevation of the improved Siphon, illustrating the same operatively positioned relatively to a ditch and the land to be irrigated.

Fig. 2 represents a longitudinal sectional view through the Siphon.

Fig. 3 represents a fragmental enlarged longitudinal sectional view through the Siphon.

Fig. 4 represents an enlarged detail sectional view through the effluent leg ofthe si hon, the pump cylinder being removed.

eferring to the drawing in detail, the

numeral '5 indicates the siphon generally which consists of an infiuent leg 1 and an effluent leg 2, the legs, as usual, being disposed at an angleto each other and connected' at their adjacent extremities by a curved portion or elbow 3. The lower or outlet extremity of the eiiiuent leg'2 is extended angularly, as indicated at 4, so as to lie approximately in a horizontal position when the siphon is in use, as illustrated in Figs. l and 2.

The terminal or outlet end of the horizontally disposed portion 4 of the effluent leg Specification of Letters Patent.

is cut or beveled at an angle of approximately forty-five degrees and is provided,

in spaced relation to the extreme end there-l of, with' an internal flange 6 providing a seat for an annular gasket 7 upon which is engaged the lower beveled extremity of the pump cylinder 8. The lower portion of the beveled edge at the outletend of the horlzontally disposed portion 4 of the effinent leg is' formed with an angular' flange retainingmember 9 adapted to engage the outwardly turned portion 10 of the adjacent beveled end of the pump cylinder 8 to form a pivotal connection, so that the pump can be. swung into position to form an air tight joint with the efliuent leg.- A lug 11 is formed integral with the lower portion of the pump cylinder 8 at a point diametrically opposite the lip or outwardly curved edge portion 10 thereof and is adapted to be engaged bythe lower cam surface formed upon the head 12 of a locking member 13 p ivotally secured at 14 tothe upper portion of the horizontally disposed end 4 of the effluent leg.

A suitable type of inwardly closing check valve 15 is arranged in the pump cylinder adjacent the lower beveled extremity thereof, and a piston 16 is reciprocably mounted within .said cylinder above the check valve. A piston rod 17vis secured to the Aupper surface of the reciprocable piston 4to be irrigated, and in use, the Siphon is setup in the position illustrated in Figs. 1 and 2, so as to immerse the inlet end of the influent pipe 1 in the water 18 contained in the ditch 19, the outlet end of the effluent leg 2 being supported upon the land by the horizontally disposed end 4 thereof. The piston 16, subse uent to immersion of the inlet end of the e uent leg 1 in the water, is reciprocated, thus exhausting. the air within the siphon and filling the latter with water drawn therein from the ditch 19. When the siphon has been completely filled with water, the locking member 13 is swung upon its pivotal axis 14, thus disengaging the cam surface of the head 12 from the lug ll and the free end of the pump cylinder 8 is swung downwardly and outwardly, as illustrated in Fig. 3, from the effluent leg 2 to the lip or outwardly curved edge 10 thereof and is disengaged from the angular flange 9 at the outlet end of the leg 2, thus permitting the'siphon to operate in the usual manner.

What I claim is:

In combination, a Siphon including iniuent and'eiiuent legs, said efliuent leg hav ing an angularv lower end for supporting it in operative position, an angular retaining fiange formed on the lower portion of the edge of the angular end, a vertically disposed pump, sad pump having an angular end and an outwardly curved portion on the lower edge of the angular end adapted to engage the angular retaining flange on the v In testimony whereof I a x my signature 25 in presence of two witnesses.'
